y Application filed December 11, 1913. Serial No. 806,054.

To all whom may concern:

Be it known that 1", JOI-IN BNYAI, a citizen of the United States ofAmerica, residing at Mclees Rocks, in the county of Allegheny and Stateof Pennsylvania, have invented certain new and useful Improvements inCutting-Machines, of which the following is a specification, referencebeing had therein to the accompanying drawing.

This invention relates to a cutting machine, particularly adapted tocutting the ends and sides of sealed envelops, and has for its object toprovide a device of such class, for the purpose set forth, which issimple in its construction and arrangement, strong, durable, efficientand convenient in its use, readily set up and comparatively inexpensiveto manufacture.

With the foregoing and other objects in view, the invention consists ofthe novel construction, combination and arrangement of parts ashereinafter more specilically described and illustrated in theaccompanying drawings, wherein is shown an embodiment of the invention,but it is to be understood that changes, variations and modificationscan be resorted to which come within the scope of the claim hereuntoappended.

In the drawing wherein like reference characters denotes correspondingparts throughout the several views Figure 1 is a front elevation of acutting machine in accordance with this invention, Fig. 2 is alongitudinal sectional view of the machine, Fig. 3 is a transversesectional view, and Fig. 4 is a sectional plan illustrating the lowercutting blade.

Referring to the drawings in detail, 5 denotes a receptacle having anextended bottom 6, an open front and an inverted V- shaped top 7 havingthe apex cutaway to provide an opening 8. Arranged within the receptacle5 is a drawer 9 having the front wall 10 thereof abutting against thebottom 6 andprovided with a knob 11.

Fixedly secured to one of the end walls of the receptacle 5 is anupright 12 having a portion intermediate of its ends, as indicated at13, overlapping the top 7 centrally thereof. Fixed to the other end wallof the receptacle 5 is an upright 14 of less height than the upright 12and which has the upper portion thereof as at 15 overlapping the top 7centrally thereof. The portion 15 of the upright 14 is bifurcated as at16.

Extending across the top 7 at the center thereof, are a pair of couplingbars 17, 18, which are arranged in parallelism and spaced from eachother. One end of the bars 17, 18, is formed integral with a portion 15of the upright 14 and the other end of the bars 17, 18, is formedintegral with the portion 18 of the upright'12. The `bar 18 is ofgreater' height than the bar 17 and the space 19 between said bars 17,18 registers with the opening or passage 8. The bar 17 is formed with aseries of transverse openings 20 having the walls thereof threaded andextending through certain of said openings 20, are coupling screws 21and extending through the other of said openings are adjusting screws22.

The reference character 23 denotes the lower cutter blade which isarranged within the space 19 and is formed with openings 24 havingthreaded walls with which engage the screws 21 whereby the blade 23 isconnected to the bar 17 and suspended within the space 19. The blade 23is formed'with notches 25 in which engage the inner end of the adjustingscrews 20.

That part of the upright 5, above the portion 13 is formed of twosections 26, 27,

which are substantially semi-cylindrical in sectional plan, and the saidsections 26, 27, have connected to their top and abutment screw 28.Arranged between the sections 26, 27, and mounted upon the portion 13 isa coiled compression spring 29, which has seated upon the top thereof acurved arm 30. The curved arm 30 extends between the sections 26, 27 andis interposed between the spring 29 and the abutment screw 28. Thespring 29 normally retains the curved arm 30 in an upright position, thearm 30 at its outer end has secured thereto a post 31 carrying a knob32. The inner end of the arm 30 terminates in the upper cutting blade33, the latter being curvilinear in contour and has its free endextending in the bifurcated upper end of the upright 14 and mounted uponthe pivot 34 which is secured to said bifurcated upper end.

The bar 18 constitutes a stop for the envelop when positioning itbetween the cutting blades to be severed. When the side or end of anenvelop is positioned across the space 13 and abutting against the bar18, the said side or end when in such position can be severed by movinthe blade 33 toward the stationary bla e 23, under vsuch conditionssevering said end, the severed end falling into the drawer Within thereceptaele 5.

What I claim is :f

A cutting device comprising a receptacle provided at its top With apassage, a pair of uprights secured to the ends of said receptaole andone of greater height than the other, a pair of parallel spaced barsextending across the top of said receptacle and connected to saiduprights, the space between said bars registering with said passage, astationary Cutting blade connected to one of said bars and suspendedWithin said passage, a cutting blade arranged above and asso- 'eiatedWith said stationary blade and pivotally connected at one end to one ofsaid uprights, a Curved arm projecting from the other end of saidpivoted blade and extending through said upright of greater height, aspring arranged in said upright of greater height to normally maintainsaid pivoted blade in an elevated position, and an abutment screwConnected to said upright of greater height and limiting the upwardmovement of said arm.

In testimony whereof I aiiix my signature in the presence of twoWitnesses.

JOHN BNYAI.
